What “UNII” is for axitinib (and where to find it)
UNII stands for Unique Ingredient Identifier, a code used by the FDA to uniquely identify active pharmaceutical ingredients. For axitinib, the UNII is listed in FDA/UNII registries and in drug product labeling databases.
To look up axitinib’s exact UNII, the most reliable approach is to search the UNII/FDA ingredient registry for “axitinib” and copy the UNII shown there.
Where people typically use axitinib’s UNII
A drug’s UNII is commonly used in submissions and datasets to connect a specific ingredient to:
- labeling/ingredient records
- drug product listings
- regulatory and interoperability systems (e.g., SPL/structured labeling data)
Related question: Are there different UNII codes for different forms?
UNII codes are ingredient-focused. If you are asking about axitinib salt vs. free base, you generally still use the UNII associated with the specific labeled active ingredient form. If you tell me whether your label uses “axitinib” or a specific salt/form, I can help you target the right lookup.
If you want, I can pull the exact UNII
Share the source you’re using (for example, an FDA label/SPL filename, a label text snippet, or a link), and I’ll help you locate the exact UNII value for the axitinib entry in that context.
